ACETYLENE-GS GEN ERATOR.

SPECIFICATION forming part of Letters Patent No. 652,098, dated J une 19, 1900.

Application lecl October 24, 1.898.

To all whom' t may concern:

Be it known that I, OLIvER DERvIN FRY, of Altoona, in the county of Blair and State of Pennsylvania, have invented a new and Improved Acetylene-Gas Generator, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and improved acetylene-gas generator which is simple and durable in construction,

automatic inoperation, and not liable to get out of order.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.

Figure l is a plan View of the improvement. Fig. 2v is atransverse section of the same on the line 22 in Fig. l', and'Fig; 3 is a similar view of the same on the line 3 3 in Fig, l.

The improved acetylenegas generator is provided with a generator-casing A, adapted to contain the water for engaging and decomposing the calcium carbid contained in the basket B, held removably on suitable supports Within the upper-end of the casing A. The removable top or lid A' of the casing A is held on a pipe C for the passage of the gas' generated by the water coming in contact with the calcium carbid, said-pipe being provided with avalve C' and a swing-joint C2, connected with a pipe C3, passing into the tank ofa gasometer D, having the usual bell D', moving in the water contained in the gasometertank. The pipe C3 opens into the lower end of a separator E contained within the gasometer-tank and submerged inthe water contained therein to separate any moisture from the gas, the moisture in condensing iiowing from the separator E-through the lower portion of the pipe C3 to a valve C4 for discharging the accumulating-moisture from time to time. In the separator E is fitted loosely a transversely-disposed zigzag partition E', each wing of which extends nearly from one side of the separator to the other, an opening E2 being at or near the upper end, so that the gas passing from the generator-casing A through `Serial No. 694,434. (No model.)

the pipes C C3 into the separator passes in a zigzag form through the latter to separate any moisture that may be contained in. the gas. The partition E' is loosely fitted in the separator to allow the separated moisture to flow down the inclined wings of the partitions and drop off the lower ends thereof to the bottom of the separator-casing, from which the moisture can be drawn off from time to time by the valve-faucet G4 in the pipe C3 at the outside of the gasometer. The gas finally passes from the top of the separator through a pipe F into the bell D of the gasometer, which in consequence of the gas rises in the usual manner and falls when more gas is withdrawn from the bell than enters the same. A standpipe G leads from the bell D above the water contained in the gasometer to carry the gas to the burners or other devices for consumption, the pipe G being provided with a suitable valve G'to regulate the outiiow of the gas from the gasometer. y

As illustrated in the drawings, two generator-casings A are employed and connected with the single gasometer D; but it ispevident that only one such generator-casing or more than two may be employed, if desired.

On the top of the bell D are secured bearings H', each carrying a. screw-rod H, formed on its outer end with a head H2 `for engaging a rod I', fastened in place y on the head by a set-screw H3, said rod being disposed vertically and having a displacer I secured on the lower end of the rod. The displacer I is preferably in the form of a closed vessel moving loosely in the receptacle J, connected at or near its lower end by a pipe J with the lower portion of the generator-casing A, so thatthe water contained therein stands at a level with the water contained in the receptacle'J, Normally the basket B is arranged with its lower end above the level of the water in the generator-casing A; but when the previouslygenerated gas is withdrawn from the gasometer-bell D' to such an extent that the latter sinks and carries the displacer I withV it then the displacer in moving downward 'in' the Water contained in the receptacle .I causes a rise of the level of the-water in both the receptacle .I and the generator-casing A, so that the water in the latter finally moves in contact with the basket B and the calcium carbid ICO A to fall.

contained therein to cause a decomposition of the calcium carbid and a consequent generation of gas, which flows from the generator-casing by Way of the pipes C CB and the separator E and pipe F to the bell D' to lift the same accordingly. When the bell D rises, the displacer I moves bodily with the bell, and consequently up in the water contained in the receptacle J, to cause the water in the latter and that in the generator-casing The Water in falling in the gen erator-casing moves out of engagement with the calcium carbid, and further generation of the gas ceases until the amount stored in the bellD is withdrawn for consumption through the pipe G.

From the foregoing it will be seen that the operation is completely automatic and no attention is required on the part of the operator except to charge the basket B with the necessary calcium carbid in the usual manner.

The screw-rod H screws in the bearing I-I', so as to bring the head H2 in proper relation to the rod I and hold the displacer I in proper position relatively to the inner wall of the receptacle J-that is, out of contact with the walls-to insure a proper working of the apparatus. Furthermore, the displacer I by the rod I can be adjusted up or down in the receptacle .I by fastening the rod I higher up or lower down in the head H2. By this construction the amount of gas stored in the bell D( can be regulated to supply the desired nu mber of burners with the necessary amount of gas. Y

The displacer I is preferably provided with a filling-plug I2 for filling the displacer with water to increase the weight on the bell D', and consequently to increase the pressure on the gas within the bell.

The generatorl A and the receptacle .Leonnected with the generator-casing, are preferably set on a suitable bracket attached to the well of the gasometer, as plainly shown in the drawings, but other supports may be provided.

By having the lid or cover A of the generator-casing attached to the swing-pipe C it is only necessary to unlock the lid and then swing the pipe C, with the lid thereon, upward to permit of conveniently removing the basket from the casing for relling, cleaning, and other purposes. If only one generator is used,.weights are used on the displacer for the other generator to properly counterbalance the gasometer-bell to obtain the desired pressure.
